GL-Inet.com creates nice clones of TP-Link WR-703 routers. They run OpenWRT out of the box, and have 2 ethernet interfaces, a 2.4Ghz Wifi (802.11n) radio, a usb2.0 port and 5 free GPIO ports. Available on dealextreme/alibaba or in the RevSpace vending machine.

Display

Widely sold as the "Nokia5110 display" (but actually most famous for being the display of the Nokia 3310), this 84 × 48 graphical display can easily be added to a GL-Inet and controlled by bitbanging SPI with the GPIO pins. It uses 4 GPIOs, leaving one vacant, if you simply tie CE/SCE to GND.

Wires soldered and plugged in, slot dremeled.

In action, after the display was hot-glued to the case of the GL-Inet.

Note: some of these PCBs come with a current limiting resistor of 150 Ω for the background LEDs, while others don't. Add your own resistor if your board didn't come with a resistor, or the LEDs will wear out very quickly.
